Nitrogen and Phosphorus Co‐Doped Graphene‐Like Carbon Catalyzed Selective Oxidation of Alcohols

Abstract

The nitrogen and phosphorus co-doped graphenelike carbon (NPG) is cost-effective fabricated by simple ballmilling and thermal treatment. The as-prepared NPG can be used as a metal-free catalyst for selective catalytic oxidation of aromatic alcohols to their corresponding acids by using TBHP and O 2 as the oxidant in water. It is observed that various aromatic alcohols bearing electron-donating/withdrawing groups can be oxidized to the corresponding acids in excellent yields. No dehalogenation and steric-hindrance effects are detected in this oxidation process. In addition, the NPG catalyst can be easily separated and efficiently reused seven times, showing good recyclability.[a] Prof.for 48 h. At the end of ball milling, oxygen and nitrogen functional groups are introduced by ball milling. The final material is further Soxhlet extracted using 1 M HCl solution to eliminate metallic impurities followed by using deionized water and ethanol washing four times and drying at 80°C in the oven in 8 h.
